Repeated Applications

Three application rates of two new growing medium surfactants were tested under two different irrigation systems on Dianthus barbatus plants. The objectives of the study were to determine if either of the surfactants influenced plant growth and development and to determine if surfactant applications decreased irrigation frequencies. The three levels of surfactant tested were 0 mg·L–1 (control), 10 mg·L–1 applied at each watering, and 100 mg·L–1 applied once a week. Each surfactant and rate was tested on hand-watered and ebb-and-flood irrigated plants. D. barbatus plants were grown for 8 weeks in 875-ml (12.7 cm) pots. Plants were watered when at least one plant per treatment showed visible wilt. Results showed that phytotoxicity symptoms occurred with repeated applications of both surfactants tested, especially at the 10 mg·L–1 rate at each watering. Application of either surfactant at 10 mg·L–1 at each watering decreased plant heights, dry weights, and plant widths, and increased phytotoxicity symptoms over the controls and the 100 mg·L–1 weekly treatments. Fewer waterings were required in surfactant-treated containers.

Abstract: Mokara Orchid is a trigeneric hybrid between the Ascocentrum, Vanda and Arachnis Orchids and was created in Singapore in 1969. Mokara is now popularly grown in Vietnam; however, research on variety or growing medium for Mokara orchid in Quang Nam has not been reported yet. The objective of this study is to identify adapted Moraka varieties and suitable growing media for the cultivation of Mokara orchids under the local conditions. The experiment was conducted from June 2016 to December 2017 at Truong Xuan Ward, Tam Ky City, Quang Nam province using a subplot design, where the growing medium is the main plot and Mokara orchid varietyis the split-plot. The experiment includes three Mokara varieties belonging to genus Mokara with 3 colors: yellow, lime, and pink spotand four growing media with different ratios of peanut shell, charcoal, and coir. The results show that the growing media significantly affect the plant height and flower yield, but they do not affect the leaf number, leaf length, leaf width, root number, and flower quality of the Mokara varieties. The varieties affect the growth and development, flower quality, and yield of Mokara. Using the same media, the pink spot Mokara variety gains the best growth and development, and the yellow Mokara variety provides the highest yield. These Mokara varieties gain the best flower quality. The growing medium with 50% coir and 50% peanut shell can be used to plant yellow Mokara (or pink spot Mokara) under the local conditions.Keywords: Mokara orchid varieties, growing medium, coir, peanut shell, yellow Mokara, pink spot Mokara

Seed germination and crop growth characteristics were determined for Tagetes spp. L. `Lemondrop', marigold; Catharanthus roseus Don. `Little Pinkie', vinca; Petunia hybrida Vilm. `Royalty Cherry', petunia; Dendranthema×grandiflorum (Ramat.) Kitamura `White Diamond', chrysanthemum; Pittosporum tobira Ait. `Wheeleri', sweet mock orange; Photinia ×fraseri Dress., photinia and Juniperus sabina L. `Moon Glow', juniper grown in various size containers containing blends of composted green waste (CGW) and UC Mix. Seed germination, plant height, and stem and root fresh and dry mass were lowest in unamended CGW. For most plants studied, a CGW: UC Mix blend containing at least 25% UC Mix was required for adequate growth and development. Germinating seeds and young seedlings were most adversely affected by unamended CGW. As plants grew and were transplanted into larger containers (10- and 15-cm pots, 530 and 1800 mL), they were better able to grow in media with higher CGW content.

Hydroponic Systems

Hydroponics is agricultural cultivation without using soil media, where the media can be replaced with husk charcoal or cocopeat media. However, hydroponics is actually the use of nutrients in a solution so that the nutritional needs of the plant are as desired. Accordingly, plant growth can be maximized. The use of media other than soil does not inhibit plant growth because both charcoal husk and cocopeat can store nutrients so that plant growth is not disturbed. This study aims to determine the response of red spinach (Alternanthera amoena Voss.) to Cocopeat and husk charcoal, and also to determine the use of DFT (Deep Flow Technique) and NFT (Nutrient Film Technique) hydroponic systems on the growth and development of red spinach. The method used was RBD where Rockwool media as a control, with 6 treatments and 4 replications. From the research results, the cocopeat media and husk charcoal media gave different results where the cocopeat growing medium was greater than the husk charcoal growing medium and the DFT and NFT systems gave significantly different results where the NFT yield was greater than DFT.Keywords: Hydroponics, Red Spinach, Cocopeat, Husk Charcoal, DFT, NFTABSTRAKHidroponik adalah lahan budidaya pertanian tanpa menggunakan media tanah, dimana media dapat digantikan dengan media arang sekam ataupun cocopeat. namun hidroponik sesungguhnya yakni penggunaan nutrisi dalam larutan sehingga kebutuhan nutrisi pada tanaman sesuai keinginan. Maka pertumbuhan tanaman bisa lebih maksimal. penggunaan media selain tanah tidak menghambat pertumbuhan tanaman karena baik media arang sekam maupun cocopeat dapat menyimpan unsur hara sehingga pertumbuhan tanaman tidak terganggu. Penelitian ini bertujuan untuk mengetahui respon pada tanaman bayam merah (Alternanthera amoena Voss.) terhadap media tanam Cocopeat, dan Arang sekam, dan juga untuk mengetahui penggunaan sistem hidroponik DFT (Deep Flow Technique) dan NFT (Nutrient Film Technique) terhadap pertumbuhan dan perkembangan bayam merah.

Composting is considered an environmentally sound and economically viable alternative for the management of organic residues. Although compost product may be used as a peat substitute in soilless culture, it generally has poor physical structure, low nutrient content, high pH, and high salt content. This study chose the coir fiber (CF) produced from coconut (Cocos nucifera) and bamboo vinegar (BV) produced from mottled bamboo (Phyllostachys bambusoides) as the media amendments, and evaluated the effects of CF (at 0%, 15%, and 25%) and/or BV (at 0%, 0.5%, and 1.0%) on the physical, chemical, and microbiological properties of composted green waste (CGW) and on the growth of peacock arrowroot (Calathea makoyana). The highest quality growing medium and the best growth of peacock arrowroot were obtained when CGW was amended with the combination of 15% CF and 0.5% BV; the lowest quality medium and the least plant growth were obtained with nonamended CGW. The optimal combination not only improved particle-size distribution and adjusted bulk density (BD), porosity, and water-holding capacity (WHC) into ideal ranges, but it also decreased pH and electrical conductivity (EC) and increased microbial numbers, enzyme activities, and macro- and micronutrient contents in the CGW. Relative to the nonamended CGW, the optimal CGW reduced the BD from 0.58 g·cm−3 to 0.34 g·cm−3 and the pH from 8.05 to 5.61, and increased the total porosity (TPS) from 48.1% to 77.0% and the WHC from 57.4% to 75.5%; the optimal CGW increased shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, plant height, crown breadth, number of leaves, and total root length by 83.9%, 77.8%, 66.1%, 65.1%, 63.6%, 73.8%, 55.6%, and 65.2%, respectively.

Various types of soils are found in India that differs widely in their physico-chemical characteristics. Their response towards plants varies for the growth and development for example, in the Jatropha plant which is an important biodiesel plant. Experiments were carried in clay pots to study the effects of four types of soils (as growing medium) viz. Alluvial, Mountain, Desert and Red on certain metabolic parameters in Jatropha curcus plant. Lot of variations with regard to certain metabolic parameters such as concentrations of chlorophyll, carotenoid and protein along with the activities of two iron enzymes i.e. catalase and peroxidase were recorded. These are discussed in the light of metabolic activity with important results being discussed.
